Description
Technical field
The present invention relates to the transmission plan in wireless communication system, more particularly to the descending scheduling for supporting narrow band transmission
Method and apparatus.
Background technology
In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) RAN (Radio
Access Network, wireless access network) in #69 plenary session, NB-IOT (NarrowBand Internet of Things, it is narrow
Band Internet of Things) set up the project.NB-IOT supports 3 kinds of different operator schemes (RP-151621)：
Independent 1. (Stand-alone) operation, i.e., dispose on the frequency spectrum that GERAN systems use.
2. protection band operates, i.e., in LTE (Long Term Evolution, Long Term Evolution) carrier wave
Protection band in untapped resource block on dispose
3. with interior operation, i.e., disposed on the resource block on LTE carrier waves
Further, in NB-IOT, UE (User Equipment, user equipment) supports 180kHz in uplink and downlink
RF (Radio Frequency, the radio frequency) bandwidth of (kiloHertz, KHz), i.e. a PRB (Physical Resource
Block, Physical Resource Block).
RAN1#83 meeting of 3GPP, NB-IOT systems it is up introduce Single-tone (single-frequency) transmission and
The concept of Multi-tone (multifrequency) transmission.Single-tone refers to UE in up transmission, can only enter on one sub-carrier
Row transmission.Present LTE (Long Term Evolution, Long Term Evolution) up SC-FDMA is then continued to use in Multi-tone transmission
The transmission means of (Single Carrier-Frequency Division Multiple Access, single-carrier frequency division multiple access),
It is transmitted on the PRB (Physical Resource Block, Physical Resource Block to) of multiple subcarriers composition.Single-frequency
One benefit of transmission is exactly that UE upstream radio-frequencies are realized simply, without PAPR (Peak to Average Power Ratio, peak
Be worth average power ratio) the problem of, and cost of implementation is low, and can keep relatively low power consumption, with improve end cell it is available when
Between.
